Good and bad are words that are tied to opinions. They exist, but their complete definition varies. In many cases, most people can agree on what is good and what is bad on a general level. For example, most people would say that death is a bad thing, on a general level. Then you get down to the details and people immediately disagree. For example, some are going to say that death itself is bad, but since they believe in heaven, they believe it leads to something good. Some are going to say that dying for your country is a good thing. The list goes on.

On a general level, good and bad does not matter. People die, species die, stuff changes for the better, stuff changes for the worse and the universe couldn't care less. On a human level, good and bad matters greatly. Since we are a species with a survival instinct, we will all continue to care about good and bad, as we see bad as a threat to the survival of our genes.
